    Areas affected...far southeast NE into western/central IA and
    northern MO

    Concerning...Severe Thunderstorm Watch 476...

    Valid 121225Z - 121400Z

    The severe weather threat for Severe Thunderstorm Watch 476
    continues.

    SUMMARY...Strong to severe gusts will remain possible across WW 476
    over the next couple of hours.

    DISCUSSION...A well organized bowing MCS will continue to quickly
    shift east/southeast across the region this morning. Measured gusts
    have decreased across IA compared to earlier gusts over eastern NE.
    Lower instability with eastward extent, as well as weakening
    low-level flow, and a persistent cluster of convection across
    central IA ahead of the main MCS, may all contribute to a gradually
    diminishing severe risk after 14z. Nevertheless, gusts of 45-60 mph
    appear likely to persist another couple of hours as convection moves
    across a moderately unstable and strongly sheared environment. There
    is some potential that after a relative morning lull, the MCS could reinvigorate later this morning as convection approaches IL, though
    confidence in this scenario is low.
